Definitions
- the object of the invention is a release mechanism for a rifle or a firearm or the like which includes a casing arranged to be attached in a detachable manner to the frame of the firearm, a locking bar for attaching the casing to the frame, a trigger and a release mechanism situated inside the casing which mechanism is arranged to transmit the movement of the trigger to the cocking means.
- the object of the invention is to present an improvement in the detachable release mechanisms of a firearm.
- Especially an object of the invention is to bring about a release mechanism which can be easily detached from the firearm while the lock of the firearm is open, but which cannot be detached from the firearm while the lock is in a closed position.
- a further object is to bring about a release mechanism which is safe and easy to adjust and secure.
- the release mechanism includes a locking stud placed within the frame which stud is movable with respect to a frame and a casing. In it's locking position the stud is arranged to prevent the movement of a locking bar as the casing is in an attached position to the frame and that the locking means include a release stem pivotally mounted in the casing and a cocking member pivotally mounted on the frame which cocking member has been arranged to rest upon the release stem, when the casing is in an attached position to the frame and the firearm is in a cocked state.
- the locking stud prevents the removal of the release mechanism from the firearm as the locking stud is in it's locking position and similarly the cocking member can be secured so that the weapon won't go off, while the release mechanism is removed.
- a firearm equipped with this type of release mechanism is safe to use.
- the lock of the firearm has been arranged to push the locking stud towards the locking bar, when the lock is in it's closed position.
- the locking stud locks the locking bar to it's position always, when the lock of the firearm is in a closed position so that the release mechanism can only detached from the firearm, when the lock is open. Therefore the firearm cannot go off, while detaching the release mechanism.
- the casing 3 with its release device and trigger is pushed towards the opening formed by the housing.
- the locking bar 4 pivotally mounted to the casing 3 includes a locking shoulder 14 which surface facing the housing 2 is oblique so that the housing's edge impinges on said oblique surface as the casing 3 is pushed towards the housing.
- the locking bar turns with respect to its pivot and allows the insertion of the casing into the housing.
- a spring 17 pushes the locking shoulder by the aid of a screw so that the shoulder engages behind edge (15) of the housing (2).
- the detachment takes place by turning the locking bar to the opposite direction and pulling the casing out of the housing.
- the release mechanism includes a locking stud 8 which is mounted in a hole 11. As the stud is in its locked position it prevents the movement of the locking bar 4.
- the hole 11 has been arranged to extend from the locking chamber to the opening formed for the casing to a place near the edge 15.
- the locking stud has been arranged movably upon a support 13 within the hole.
- the locking shoulder's surface 16 is arranged obliquely and a protrusion with a corresponding oblique surface 19 has been arranged on the end of locking stud 8 facing the casing 3.
- the lock 9 of the weapon is in it's locked position above the hole 11 so that the lower surface of the lock 9 presses the locking stud 8 towards the locking bar 4 so that the surface 19 of the locking stud engages on the surface 16 of the locking bar and prevents the movement of the locking shoulder 14 and the removal of the shoulder from the edge 15. This prevents the detachment of the casing from the fire-arm.
- the lock 9 is in it's open position the locking stud 4 is free to move upwards as the locking bar is turned, thus, making it possible to detach the casing 3 from the weapon.
- the cocking means include a release stem 6 pivotally mounted on the casing and a cocking member 7 pivotally mounted on the frame 1. Beneath the cocking member 7 a safety pin 21 is mounted on the frame. The safety pin can be moved to a position under the locking member 7 in order to hinder the latter's downward movement and secure the firearm. This prevents the firearm from going off, while removing the casing of the release mechanism from the firearm.
- the release mechanism includes a trigger piece 25, a cocking arm 26 as well as adjusting springs and screws.
- the tip of the release step 6 rests upon the rocking arm 26.
- the actual threshold for release is formed between between the release stem 6 and the rocking arm 26.
- the screws 128 and 27 can be adjusted through holes situated on the casing.
- a suitable counterforce is adjusted to the release stem 6 by a spring screw 22 so that the force caused by the locks striking spring which acts through the cocking member can be advantageously compensated for.
- the resistance of the trigger can be adjusted by a spring 28.
- the upper part 25 is connected to the trigger, and the rocking arm 26 is pivotally connected to the casing and cooperates with the upper part 25 and the release stem 6.
- the centers of gravity of said upper part 25 and release stem 6 have been arranged with respect to their pivots so that the cocked arm won't go off though its rear is hit on the ground.
- the upper part 25 has been formed so that its centre of gravity is high with respect to its pivoting axis so that the upper part moves away from the rocking arm 26 if an impact is directed to the rear of the firearm 26.
- the rocking arm is formed so that in case an impact is directed to the rear of the fire-arm, the said arm is arranged to move towards the release stem 6.
- the weapon won't go off.
- the trigger is manufactured of light material so that it won't effect unfavourably the weight ratios mentioned above.
